keel becomes visible in the suture of the following whorl. Base of the 

 whorls ornamented with smaller keels. Aperture of the (last preserved) whorl 

 rounded, somewhat greater in height than width (fig. 12 a). 



Amberleya sp. belongs to the group of 

 Aniberleya capitanca Milnst. sp. The occur- 

 rence of this group in Jurassic deposits of 

 arctic regions is already noted by TuUberg 

 {Turbo capitaneus from the Oxfordian of 

 Besimennaja Bay, Novaja Semlja).

sea, north-west of Elmwood, on July 12th, 1896. As no remains of the 

 rock, where the shell originally was embedded, are preserved, Amberleya sp. 

 might have been washed out from the soft clay, which constitutes the greater 

 part of the strata underlying the basalt at Cape Flora. 



CEPHAJL OFODA. 

 AMMONOIDEA. 



Judging from the number of species and individuals. Ammonites are the 

 group of animals most largely represented among the fossils collected at 

 Cape Flora. 



The material before me shows that the different rock-types from the 

 neighbourhood of Cape Flora are, in varied degrees, rich in ammonites. 

 While ammonite fragments occur very often in the pieces of clay sandstone, 

 clay, and stone marl, I found no trace of ammonites in the hard, finely-grained, 

 very sandy marl No. 4 containing numerous lamellibranchiate, brachiopod, and 

 belemnite fragments. From this fact, however, it cannot without hesitation 

 be asserted that this rock is entirely destitute of ammonites. Newton^ men- 

 tions a fragment of an undetermined ammonite ("allied to A. Gowerianus"), 

 which was found among the loose fossils weathered out of the strata "west 

 of Elmwood", where this rock occurs in place at an inconsiderable height 

 above sea-level. Possibly this ammonite fragment originated in the sandy, 

 hard marl.
